I'm interested in doing a fantasy mod. One idea was maybe have different civilizations based on different fantasy races. My first thought was a Vampire civilization. I wanted to create a unique unit which could have a couple abilities: It heals fully after defeating an enemy unit, and the unique unit could cause an enemy unit to join the side of the vampire civilization. I'm sure this is possible, but I have no idea where to start. Any help would be appreciated. Be as technical as you wish, I have sufficient programming expierence, but no mod expierence.
